HydraPaper is a wallpaper manager, specifically designed to work around the lack of functionality of many desktop environments to set a different wallpaper for each monitor in a multi monitor setup. It accomplishes this by scaling and merging different wallpapers into a single one and setting it as spanned.
It currently supports various desktop environments, including GNOME, MATE, Cinnamon and Budgie. Experimental support is included for the sway window manager.

I was looking for software that can set different wallpapers for different monitors. Despite Nitrogen and Variety (I'm not sure about the latter) can do exactly that, it won't work in Cinnamon. Hydrapaper worked for me because I think it merges the wallpapers as a global image but it doesn't actually set a specific wallpaper to a monitor. So yeah, it worked for me! (installed the flatpack btw). Personally I would say that this can be a very good idea to be added as a pre-installed program.
I agree with hopelessdecoy, this would make a better default for Mint. It just does what I want it to.
Works for me and does an amazing job, Mint should think of making this it's default wallpaper engine :)
The only thing that would make this app better would be adding an option that allows the user to randomly change the wallpaper on each monitor at a specified time interval.
Just to say that it works fine with Linux Mint MATE 20 with images stored in default "picture" folder. Thanks! :)
As mention a good idea but can't add an additional folder like usr/share/backgrounds. The add screen does not list this folder to choose from. Using Mint 19.3 with Cinnamon 4.4.8. But does the basic job I wanted, but with pictures in the pictures folder only.
A very good idea but unfortunately, it isn't compatible with Linux Mint Mate. Tried it in Ubuntu 18.04 which is Gnome 3 and it screwed the entire system up. Assuming it is compatible, it isn't very friendly with Gnome 2 or 3. Perhaps some lessons could be learnt from KDE.
